test to see if the circuit is complete using either a test meter or a 12v light bulb and a piece of wire if you connect between the two connections on the rear of the cigarette lighter you will either get a 12v(could possibly be up to 13.8v) reading or the light will glow, if this happens replace lighter unit approx £4-£5 at any motorists accessories shop ie Halfords etc.
